U.S. imports of Nickel & Nickel Alloy Tubes, Pipes & Fittings (SITC 68322) totaled $18.9M in August 2026, imported from 38 countries.
Importers of Nickel & Nickel Alloy Tubes, Pipes & Fittings paid $2.4M in duties in August 2026, an average duty rate of 12.45% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Nickel & Nickel Alloy Tubes, Pipes & Fittings imports of $18.9M in August 2026 ran 24% below the year-to-date monthly average of $24.8M.
Last updated: August 2026 dataNickel and nickel alloy tubular products — including seamless and welded pipe, as well as couplings, elbows, and sleeves — are engineered for aggressive service environments in chemical plants, desalination units, and heat exchangers where carbon steel would corrode rapidly. Classification under 68322 covers both the tube and pipe forms and their associated fittings, so importers must confirm whether a shipment mixes product forms that might require separate line-item declarations. Section 232 tariff exposure is a live consideration for many origins, and buyers should verify whether product-specific exclusions apply to their alloy grade and dimension.

Yes — tube or pipe fittings such as couplings, elbows, and sleeves made of nickel or nickel alloy fall within this heading alongside the tubes and pipes themselves. However, if fittings are imported separately from the pipe, they should still be declared under 68322 rather than under a general fittings heading, provided they meet the nickel or nickel alloy material definition.
ASTM B161 (commercially pure nickel), B165 (Monel alloy), B167 (Inconel alloy), and B444 (Alloy 625) are among the most frequently cited specifications for seamless nickel alloy pipe in US procurement. Importers should ensure mill certifications reference the applicable ASTM or ASME standard, as end-users in pressure-vessel and heat-exchanger applications require full material traceability.
